Frequently Asked Questions

VideoToAudio is a free online tool that converts video files to audio formats. It runs entirely in your browser using WebAssembly technology, which means your files are processed locally on your device and never uploaded to any server.

Absolutely. Your files are processed entirely in your browser and never leave your device. We cannot see, access, or store your files. This makes VideoToAudio one of the most private video to audio converters available.

Yes, VideoToAudio works on modern mobile browsers including Chrome, Safari, and Firefox on both iOS and Android devices. However, for best performance with larger files, we recommend using a desktop or laptop computer.

VideoToAudio supports most common video formats including MP4, AVI, MOV, MKV, WebM, FLV, WMV, and more. If your browser can play the video, our converter can likely process it.

You can convert your videos to MP3, WAV, AAC, OGG, and FLAC formats. Each format has its own advantages: MP3 for universal compatibility, WAV for lossless quality, AAC for efficient compression, OGG for open-source projects, and FLAC for audiophile-quality archiving.

For most users, MP3 is the best choice due to its universal compatibility across all devices and platforms. Choose WAV or FLAC if you need lossless quality. AAC offers better compression than MP3 at the same quality level. OGG is great for web applications and open-source projects.

Our converter extracts the primary (default) audio track from your video. If your video has multiple audio tracks (like different languages), the main track will be converted.

VideoToAudio uses FFmpeg compiled to WebAssembly, which allows powerful media processing to run directly in your browser. When you upload a file, it stays on your device while the conversion happens locally using your computer's processing power.

We recommend files under 500MB for optimal performance. Since conversion happens in your browser, very large files may take longer and depend on your device's processing power and available memory.

Conversion speed depends on your device's CPU, available memory, and the size of your video file. Older devices or files with high resolution/bitrate will take longer. For best results, close other browser tabs and applications during conversion.

VideoToAudio works best on modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your browser for optimal performance. Some older browsers may not support WebAssembly.

Yes! Our converter includes a built-in timeline trimmer that lets you select the exact portion of audio you want to extract. Simply drag the handles on the timeline to set your desired start and end points.

Make sure your file is a valid video format and not corrupted. Try refreshing the page and uploading again. If the issue persists, try using a different browser or check if your file can be played in a media player.

Conversion can fail due to corrupted files, unsupported codecs, or insufficient device memory. Try with a smaller file or different video. If you continue to have issues, the video may use a codec that isn't fully supported.

Audio quality depends on the original video's audio track. Our converter preserves the original quality and uses high-quality encoding settings. If the source video has low-quality audio, the output will reflect that.

Large files can consume significant memory. Try closing other tabs and applications, using a smaller file, or splitting your video into smaller segments before converting.
